On-shore sail shade

ABSTRACT

An on-shore sail shade is provided which includes a sail secured to a mast and a boom with the sail shade being positioned on a patio or the like to provide desired shade protection. A foot portion of the sail is located close to the ground or supporting surface so that the sail shade will provide the desired shade during all daylight hours.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an outdoor shade device and more particularly to a shade sail to provide shade in outdoor commercial and/or residential settings.

2. Description of the Related Art

Many types of outdoor shading devices such as awnings or other overhead structures have been previously provided. However, the awnings or other overhead structures are not effective during important times of the day as the result of the angle of the sun. An example would be a west-facing patio in an early evening scenario where sunlight has dropped below any existing shade structure currently on the market.

SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.

An on-shore sail shade apparatus including a mast support which is associated with a supporting surface with the mast having upper and lower ends. The lower end of the mast is secured to the mast support and extends upwardly therefrom. Preferably, the mast is comprised of a plurality of mast sections to facilitate the assembly and positioning of the mast. An elongated, horizontally disposed boom, having inner and outer ends, has its inner end secured to the mast above the lower end thereof and extends horizontally therefrom. A flexible, generally triangularly-shaped sail is provided having a foot portion with inner and outer ends, a luft portion having upper and lower ends, which extends upwardly from the inner end of the foot portion and a leech portion extending downwardly and outwardly from the upper end of the luft portion to the outer end of the foot portion of the sail. The foot portion of the sail is secured to the boom. The upper end of the luft portion of the sail is secured to the mast adjacent the upper end thereof. The boom is horizontally rotatably movable between various positions either by the boom being rotatably secured to the mast or by rotating the mast and the boom affixed thereto. The boom is movable between various positions to enable the said to be positioned in various shading positions.

The outer end of the boom is fixed to an anchor which may be of various designs to maintain the boom and sail in the desired shading position. The sail and the boom may be removed from the mast so that a flag, banner, sign or other structures may be supported from the mast.

It is therefore a principal object of the invention to provide an improved outdoor shade device.

A further object of the invention is to provide an outdoor shade device which includes a mast, boom and a sail.

A further object of the invention is to provide an on-shore sail shade apparatus which may be selectively positioned in various shading positions.

A further object of the invention is to provide a sail shade apparatus wherein the sail thereof is comprised of an air permeable or breathable material.

A further object of the invention is to provide an on-shore sail shade apparatus which is easily assembled and disassembled.

These and other objects will be apparent to those skilled in the art.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

The on-shore sail shade apparatus of this invention is referred to generally by the reference numeral 10. Apparatus 10 includes a vertically disposed mast 12 having an upper end 14 and a lower end 16. The lower end 16 of mast 12 is secured to a hollow, tubular mast support 18 which is preferably embedded in the ground or concrete material 19 as seen in FIG. 2. The mast support could also be a floor anchor, fastening plates, clamps, brackets and footings as long as the mast which is secured thereto may be rotated in a 360° fashion. Mast 12 preferably includes an annular shoulder 20 extending therefrom which rests upon the upper end of support 18 as also seen in FIG. 2. Preferably, mast 12 is rotatably received within support 18.

A clevis 22 is secured to mast 12 closely adjacent shoulder 20. Bracket 24, or similar structure, is secured to mast 12 above clevis 22. Cleat 26 is also secured to mast 12 and is adapted to have the halyard 28 secured thereto. Pulleys 30 and 32 are rotatably mounted at the upper end of mast 12 and have the halyard 28 extending therearound. One end of halyard 28 has a slide or other type of connector 34 secured thereto.

The numeral 36 refers to a boom having an inner end 38 and an outer end 40. Inner end 38 is pivotally secured to clevis 22, about a horizontal axis by means of pin 42. The numeral 44 refers to a generally triangularly-shaped flexible sail having a foot portion 46, a luft portion 48 and a leech portion 50. Preferably, sail 44 is comprised of a breathable or air permeable material to permit some air to pass therethrough while still providing the needed shade. Further, sail 46 is preferably comprised of a material which will accept signage and advertising print thereon.

Foot portion 46 of sail 44 is secured to boom 36 by rings or loops 52 or other suitable fasteners. The outer end of foot portion 46 is selectively removably fixed to foot portion 46 to maintain foot portion 46 in a generally taut manner. The upper end of luft portion 48 is attached to the connector 34 by means of a snap, buckle or loop 54.

The outer end of boom 44 is selectively removably secured to an anchor 56 by a rope or by a rope and pulley device 58 to maintain boom 36 in its desired position. Anchor 56 may take many shapes or configurations. Anchor 56 could be of a screw type as seen in FIG. 4 or could be embedded or recessed in the ground or patio as indicated by the reference numeral 56′. The anchor could also be a weight such as indicated by the reference numeral 56″. Further, the anchor could be a cleat such as indicated by the reference numeral 56′″. The anchors are located at various positions relative to the mast 12 so that the boom 36 and sail 44 may be selectively positioned to provide the desired shade at different times of the day.

FIG. 3 illustrates a pair of the apparatuses 10 mounted on a patio or the like. The sails 44 of the apparatuses may be selectively positioned to provide the necessary shade by rotating the masts 12 to the proper position and then anchoring the outer ends of the booms 36 to the anchors 56. Preferably, the mast 12 is comprised of a plurality of mast sections which may be connected together to aid in the ease in the erection and lowering of the same. When the sail is not being used, it may be lowered to the position illustrated in FIG. 5. Further, the boom 36 and the sail 44 may be removed from the mast 12 so that a flag 60 may be supported upon the mast 12 at the upper end thereof as illustrated in FIG. 6. A flag 60 could be replaced by other things such as banners, etc.

Thus it can be seen that a novel on-shore sail shade apparatus has been provided with the foot portion of the sail being located close to the ground so that the angle of the sun's rays will not pass therebelow. It can therefore be seen that the apparatus of this invention accomplishes at least all of its stated objectives.
